Observation: CV-1 Chamber & inlet Bowl-turn is impressive.
YET, SPOTTS had KRE Wide & Tall Port heads all over his shop, and (I forget which one) has a substantially-similar Heart-like Chamber that keeps the Plug dry, and full-daylight wide Intake runner that got me to thinking of the substantive similarity to the CV-1.
================================================== ===============
REMINDER: 95% of the CYL head Performance value is the HALF-INCH before & after the Intake Valve seat.
